Leigh Brackett, George Sanders

Give a man enough rope and he'll hang-someone! A book written to
cash in on the success of film actor George Sanders, and
ghost-written by Leigh Brackett, whom the supposed author claims
never to have met. Stranger at Home is the story of Mike Vickers,
back home from the dead, and trying to find out who among his
family tried to get him out of the way in the first place.
